Hunter skill description improvements

Sentinell Strike
It should be explained in the skill how much energy it costs to cast, that you can cast it instantly and how much swiftness is needed to cast it instantly.

Sentinell Call
Should explain the energy cost, how long it lasts in time and how many attacks it should preform before despawning and maybe that if either condition is met it will dispawn, also that it can stagger and snare enemies and what type of damage it deals similar to the text on Sentinel Cyclone.
